I'm starting to wonder why I even post here. Every post I make is followed by someone telling me I'm wrong. [:)]
brasspile, the best way to build muscle is NOT by using a low carb diet and only eating 150 grams of protein a day. That's really not even enough for the average person trying to loose weight. It's really pretty simple. In order to grow, calories consumed must be greater than calories used every day. 150 grams of protein a day and few carbs a day isn't even close to 1500 cal. Unless his metabolism is unusually slow, there is no way a 6' tall 170 lbs man will grow on such few cal/day. He's not seeing improvements in his workouts now and a big reason why is because he's not eating enough.
norman74, trust me, if you start eating more you'll see improvements. Start eating every 3 hours. Don't try to jump to eating 250 grams per day in one day. It takes time for you body to get used to the added calories. Just eat a little more every day until you get there. I'm eating 300 grams of protein, 600 grams of carbs, and about 100 grams of fat per day, so I know it's possible. And that actually isn't filling me up, so I'll probably add 500 cal/day next week. Also, don't leave out the carbs. You should aim for about 550 grams of carbs per day. You should never get hungry and you should always feel full, that's the best way from preventing your body from going into a catabolic state. If your body knows there's plenty of food available, it will grow. And avoid supplements/weight gainers/protein shakes. Eat real food. It's much better. Oh, and one more thing. The protein you see on the nutrition label from the cereal bar and the potato salad probably doesn't have a complete amino acid profile, so you shouldn't count it. Only count protein grams from chicken, turkey, pork, beef, fish, eggs, and dairy.
